Air source heat pump is an energy-efficient equipment that transfers heat from ambient air to high-temperature heat sources.
Our GRAD air source heat pumps and air cooled chillers boast nearly 20 years of practical engineering experience. Integrated with mature design, manufacturing and application technologies, the units feature core advantages including strong heating performance at low temperatures, multi-layer anti-freezing design, intelligent defrosting and smart control systems.
Key Features & Advantages
Extreme Temperature Resilience
Stable heating operation at -20°C (-4°F) , with hot water supply up to 60°C (140°F). Cooling capacity boosted by 12%+ via advanced heat exchange optimization, while low-temperature heating COP improves by 20%+ compared to standard units. Operates reliably across -35°C to 48°C (-31°F to 118°F) ambient range, covering 95% of global climate zones.
Modular & Flexible Design
Composed of independent, interchangeable modules for scalable capacity (easily add/remove modules to match load demands). No dedicated or cooling tower required—units install on rooftops, ground levels, or compact pads, saving 30%+ installation space. Any module can act as master; if one fails, others continue running for zero downtime.
Industry-Leading Energy Efficiency
70%+ lower operational costs than traditional coal/gas heating systems. Intelligent fuzzy control system auto-starts/stops modules based on real-time load, ensuring optimal efficiency at all times. Smart rapid defrost technology minimizes energy waste in winter, maintaining consistent heating performance.
Premium Quality & Durability
Equipped with imported hermetic scroll compressors , high-efficiency finned heat exchangers, and corrosion-resistant hydrophobic coatings (20x better salt spray resistance than standard coils). Multi-level safety protections (overpressure, overheating, low-temperature freeze guard) ensure long-term stable operation. Full compliance with ISO, CE, and GB/T 18430.1-2024 standards, certified for global commercial use.
Smart & User-Friendly Operation
Advanced SYS IoT remote monitoring system enables real-time status tracking, fault diagnosis, and alert management via mobile/PC. Centralized control with 7+ operation modes for customized energy savings. Low-noise fan design (≤65dB) ensures quiet operation in noise-sensitive areas.
